ATENT WILLIAM F. HUTOHINSON, OF LYNN, MASSACHUSETTS, ASSIGNOR TO \VARREN B. HUTCHINSON, OF PASSAIO, NEWV JERSEY.

SPECIFICATION forming part of Letters Patent No. 433,788, dated August 5, 1890.

Application filed November 21, 1889.

To all whom it may concern:

Be it known that 1, WILLIAM F. HUTCHIN- SON, a citizen of the United States, residing at Lynn, in the county of Essex, in the State of Massachusetts, have invented a new and useful Tooth-Pick Machine, of which the following is a full, clear, and exact description.

My invention relates to that class of toothpick machines in which the tooth-picks are cut from thin strips or veneers of wood, the width of the Veneers corresponding to the lengths of the tooth-picks. These veneers are turned from the log in long ribbons or strips in a manner well known to the trade and needing no detailed description.

The object of my invention is to provide a machine that shalleut these tooth-picks very rapidly and to provide means to prevent them from sticking between the knives of the machine,

To this end my invention consists in a frame carrying two rotary drums, the larger of which has a series of knives arranged around its entire periphery the width of a tooth-pick apart, and having means, as hereinafter described, for expelling the tooth-picks from between said knives, and the smaller of which acts as a bearing for the knives. This construction will be hereinafter fully described,

0 and more specifically pointed out in the claims.

Reference is to be had to the accompanying drawing, forming a part of this specification, which is a perspective view of the machine,

3 5 with portions broken away to show the manner of expelling the tooth-picks, and in which like figures of reference indicate correspond ing parts.

The larger drum or cylinder B is hung in the frame A and turns upon the shaft 0. The shaft 0 is provided with a pulley, (not shown in the drawing,) to which power is applied to run the machine.

The knives b are a little longer than a toothpick, and are placed in grooves in the face of the cylinder B the width of a toothpick apart, and are held in position by the flanges D, which clamp onto the ends of the knives. Between the knives b are rods or wires d, which lie against the face of the cylinder B, and the ends of which project be Serial No. 331,070. (No model.)

yond the ends of the knives b,and are retained by the annular grooves e of the collars E. These collars E are rigidly attached to the frame A by the screws f, and the grooves 6 form the same circle as the cylinder B, except that at the under side of the cylinder B the grooves e swell out in the form of a cam, as indicated by the dotted line at the point 1, so that as the cylinderBrevolves the ends of the rods d will follow the grooves c, and where the grooves e swell out, as described, the rods 61 will be forced out to the edge of the knives b. Y

The frarneA is provided with two upwardlyextending arms, in which is hung the drum H, which turns upon the shaft I. This drum may be made of wood, rubber, rawhide, or any suitable material, and should bear against the edge of the knives b.

The machine, being set in motion, is oper ated as follows: A strip of veneer is inserted between the knives b and the drum H, and 'as the drums revolve the veneer is cut into tooth-picks by the knives b pressing against the drum H. The tooth-picks will thus be forced between the knives (9 upon the rods cl, and as the cylinder B revolves the ends of the rods cl will follow the grooves 6 till the projecting portion of the grooves c at the point l is reached, when the rods cl will be forced out, as described above, forcing the toothpicks from between the knives. As the cylinder revolves further and the grooves e resume their circular shape, the rods cl, following said grooves, will be forced back into position against the face of the cylinder B.

Instead of having the grooves e extend entirely around the collar E, the inner face of the grooves could be dispensed with except 0 for a short distance at the bottom of the collar, Where the cam portion of the groove is located. i

The cylinder B, knives b, and drum H are arranged substantially as shown in a former 5 patent to me, dated May 28, 1889, No. 404,282, and I do not claim such as myinvention; but

WVhat I claim, and desire to secure by Letters Patent, is x 1. In atooth-pick machine, the combination, with a revolving cylinder, having knives the width of a tooth-pick apart arranged around its periphery, and a rotary drum as a bearing for said knives, and having rods between the knives, with their ends extending beyond the ends of the cylinder, of a collar rigidly at tached to the frame of the machine, having its inner surface provided with an annular groove adapted'to receive the ends of said rods, said groove having a earn-like projection adapted to force said rods to the outer IO edge of the knives, substantially as described.

2. In a tooth-pick machine, the combination, with the cylinder 13, having knives b'arranged around its periphery, and having rods d between said knives, of means, as collar Eand groove 6, for forcing said rods to the outer I 5 edges of the knives, substantially as described.
